Explanation:
If friction was absent, the chalk deposits would not stick to the board and no mark would be left behind. This would have made it impossible to write with the chalk on the blackboard.

Answer:
When you scribble chalk on blackboard friction is formed and the main use of this friction is to leave a mark on the board/write on the board.
Explanation:
There are mainly 3 types of forces involved in your action- 1) Normal force, 2) Frictional force 3) Muscle force
The normal force formed is responsible for seperating the chalk dust from the chalk. The frictional force produced in the process of scribbling is responsible for reducing the mass and shape of the piece of chalk. And the muscle force that you apply on the board WITH the chalk helps to leave the chalk dust on the board and not letting it to fly away.
Please mark as brainliest because it took a long time to type.
